# Qualcomm SDK (QSDK) sysupgrade compatible images for IPQ40xx, IPQ806x
# and IPQ807x use FIT format together with 'dumpimage' tool from U-Boot
# for verifying and extracting them. Based on 'images' sections names,
# corresponding mtd partitions are flashed.
# This is a simple script for generating FIT images tree source files,
# compatible with the QSDK sysupgrade format. Resulting images can be
# used for initial (factory -> OpenWrt) installation and would work
# both in CLI and GUI. The script is also universal in a way it allows
# to include as many sections as needed.
